u To au whont it may concern.- v

- Figure 1 is a lngitudiu-al vertical section IofY my invention taken in the Aline at' az, Fig. 2; Fig; 2, a plan or top View ofthe same, partly in section. l l e Similar lettersof reference indicate correspending parts in the two. figures.

Oil-stcnes have hitherto been fitted in wooden. blocks and provided with a wooden covei` to protect them from dust'and preserve them from breakage. The stoneshave eitherbeen iitteg-permanently inthe blocks or adjusted "snugly within' them, so as to be in Contact with vthawood.

This Inode of boxing or incasing oil-stones is'attended with the following disadvantages First, ,the wood absorbs Y the oil which escapes'from-the stone, and soon becomes completely saturatedwith it, so that it' cannot be handled without soiling the fingers; second, thestone being either permav nently tted in the block or adjusted snugly within it, cannot be readily removed and turned so as to haveafresh sideplaced up' permet- My inventionis designed to obviate these difficulties; and'Y it consists in having a box vcomposed of castimetal and of two equal longitudinal parts, one' of which'is provided internally with projectionsand a set-screw for A the proper adjustment of the stone within. it,

and the other serving as a cover, the latter as welles4 the part first'mentioned being-profvided with knifeiedge projections to prevent 4them vfrom slipping when in use, as hereinafter fully set forth..

'ro enabiethoseski-i1ed in Athe art to "fully 4.understand and construct my inv ention, I 'will 'proceed to describe it.

A represents the lower, and B the upper, part of a' quadrilateral, cast-metal box of any suitable or' desired dimensions.. rIl he lower part, A, or" vthe box has upright projections a on its bsttmpfor the stone to rest upon, and

and exact description of ;the same, f reference being had to the accompanying drawithasprojections b at the inner sideofone .end to serve as bearings for oneend of/the stone, the opposite end of the part A having a set-screw, C, passing horizontally through it and bearing ,against the opposite end of the 1 stone. A

The stone, designated by lD, is somewhat smaller than the interiorfof the part Aof the box, so that a-space will .be allowed between the sides of the latter, the, projectionsa ad- -mitting of a s pace being allowed underneath the stone, and the projectionsb effecting the same obj-ect at one end of it, while the d irnensions of the. stone admit of a space `ageing at its opposite end, against which the set-screw C bears. (See Fig. l.) The stone D, it will be seen, is retained firmly in the partA of the box by screwing up the set-screw G,and the 'stone may, by loosening or unserewing *the setfscrew C, be` readily lifted out of A' and turned either side uppermost, and again secured in A. Thus, when one sidejof a stone becomes worn un-. evenly by use, a fresh'planesurface bythe turning of the stone maybe readily adjusted in position for use.

The-upper part,l B, of the box is thecove'r,

.which simply rests on the top of A, and is Ifetained in position by a pendent knife-edgc'zdP projection, c, at each end, saidjg'irojectionsex#` tending the whole'- widthof the cover, and when B is placed on A fitting within the upper parts of the ends of the latter, as shown. in Fig. 1. The lower part,' A, is provided;l

with'similar projections, d, at its ends. projections d prevent thepart A from slipping on the surface on which it restswheirthe stone is used. The projections c of the' part or cover B'perform asimilar office for the latter,which has a strap, E, cemented or/otherwise secured -to its upper surface for putting a fine edgev'on the tool after it has been sharpened on the stone. v

From the above descriptionit will be seen that the oil which drips from the stone will pass down-within the part A, instead of run- Aning down on the outer sideof it, and said part as well as the stone may be cleaned with the greatest facility .by simply removlng the stone from A. Thus .the stone' and box may with but little trouble always be keptclean and in a proper condition foruse.

The parts A and B are designed to be of l'thestone in position andv'dmitting of au oilequal dimensions; and stones of square form passage all around it, and theother, B, madein their transverse section would-'be preferable, to serve .as a cover, substantiallyas set forth. to admit of' ogy one of their sides being ad-' 2. The knife'.edged projections d c, when j usted uppermost, ns'ed in combination with and formedfon or v Having thus described my'inventiomwhat I l"cast with the parts A B,v for the purpose speciclaim' as new, and desire to Secure by Letters fied. o Patent, is-' l l 1. .A-box or case for oil-stones; composed of two castlmetal parts, AB', one of which, A, VVitnesse'si:` A. is provided internally with projections a band GEO.
